The company said the appointment follows a “lengthy and rigorous” tender process. It will manage the two mandates, details of which were not disclosed, for a fixed term of five years from its office in the Isle of Man, which was established in 2013. 

WH Ireland's private client arm, which provides wealth management and wealth planning services from the UK and the Isle of Man, has around £2.5 billion ($3.6 billion) of assets under management or influence.

“This is a strong endorsement of the Isle of Man office and the WH Ireland Group. Our international division has grown significantly from two to eight staff since the office launched in February 2014. The appointment to manage the two mandates gives us a sound platform to continue the growth of our international business and further strengthen our Isle of Man team,” said WH Ireland's group chief executive, Richard Killingbeck.
